FRUITSTONING MACHINE.

SPECIFICATION forming part of Letters Patent No. 460,740, dated October 6, 18 9 1.

Application filed February 10, 1891. Serial No. 380,953. (No model.)

To all whom it may concern:

Be it known that I, JOHN SMITH BRIGGS, a citizen of the United States, residingat San fornia, have invented an Improvement in Fruit-StoningMachines; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to an apparatus for cutting fruit and removing the stones or pits therefrom, it being especially applicable to such fruits as apricots, peaches, plums, and the like.

It consists in certain details of construction, which will becmore fully explained by reference to the accompanying drawings, in which-- Figure 1 is a perspective view of my apparatus. Fig. 2 is a side elevation especially showing the relative arrangement of the rotary cutting-disk, knife, feed and transfer chutes, and other connected parts. Fig. 3 is a plan view showing the arrangement of the cutting-disk, yielding knife, and the devices for removing the fruit from the pits.

A is a frame-work of any suitable construction adapted to support the necessary machinery.

B are the standards of the iron frame-work, having the shaft 0 journaled at the top, and this shaft has fixed upon it the rotary cutting-disk D and is driven by hand or other power. This disk has four or any other suitable number of projecting cutters E,.having sharp edges, and it rotates in a plane paris supported upon a fulcrum-shaft G from the main frame. The rear end of this knife has which is by the side of the rotary disk and which has a sharp edge upon it is forced upward, so that the fruit, when delivered, will be cut by the edges of the disk and cutters E and also by the blade F.

The fruit is delivered to the cutter through a V -shaped trough I, and this trough has within it a sliding or reciprocating side J, which rests against one side of the trough, and when the fruit is placed in the trough;

one side of it rests against the side he trough and the other against this reciprocating plate. Theshape of the trough is such as to cause the fruit in moving down to assume a position with its longer axis in the plane of the cutters, to which it is presented.

K is a link or correcting-rod, which unites the plate J with an oscillating frame L, jourupon a shaft M,'which is supported in up- -wardly-projectiug lugs B of the frame B, as

shown.

The frame L has an arm N projecting paral-' lel with and close to the disk D, and this arm is engaged as the disk rotates by the projecting pins 0, so that as each pin strikes'the arm N it pressesit downward and tilts the rectangular frame L about its fulcrum-shaft M. As soon as the pin 0 has passed the arm N a spring or weight P, which is connected with the rear end of the frame L, will act to draw the frame down again and throw the arm X up ready to be engaged by the next pin 0 This action operates, through the connectingrod K, to oscillate the plate J within the trough I, and it thus serves to move the fruit forward and prevent its sticking in the feedtrough.

Connected with the frame L is an elastic forked plate Q, the forked end of which pro jects down into the trough I and prevents more than one fruit at a' time from passing out of the discharge end of the trough. This fork is alternately raised and depressed by the oscillations of the frame L, and when it is raised it allows a single fruit to escape from the lower end of the trough I and be deli ed into a short carrier-trough R, which is ured to the guide-arms L, attached to the front end of the frame L and extending downwardly through staples or guides upon the sides of the knife-bar F. Thetilting of the frame L moves these arms L alternately up and down, and they carry with them the short carrier-trough. This trough is depressed so as to stand opposite-the discharge end of the trough I, and it -receives a single fruit within it. As the arm'N- is leased from the pin Othe frame. rises and withit the 'rier-trough R, which forces the fruit against the sharp cutters E of th', disk D, and as the disk continuesto rotate it presses the fruit upon the yieldingknife-F, which ting-disk. When the fruit is first seized by the cutters, the carrier is again moved down so as to relieve the fruit from pressure and prevent its being bruised, and the cutters then remove it easily from the carrier. By means of the cutters of the disk, which surround a considerable portion 'of thefruit, and the blade F, which occupies the opposite side, the meat is cut through to the pit, and the .pit is tein vorarily held between. the edge of the blade and the notch for-med by the cutters E, while the meat-is pulled elf the fruit by means of the semicircular stripper-plates S. .These plates have their outer edges hinged, as shown atT, and their inner edges are curved so as tolie in close contact with the knife F and the revolving disk, so that as the fruit is carried forward by the movement of the disk the inner dges of these plates will be hooked into the out which has been made around the p tand as the pi 'wrrier f rward by th further movement of the-disk the plates S will move backward and outward about their;

hingesT and in separating will pull the meat on? the p t Sp ings U are c nnec e with these plates S, and as soon as the plates are freefrom the f it an the pit hesprings will draw themcbeck a sip-inpogitionto receive the next fruit; eneath these platc s is the inclined table formed of the. twcover-I ng pl es VV' Aton' end he -n ates are connected with a bell-crank lever W, and

at he o her and they a e connect d by a ms" Y with th r rve Plates .3 5 a a t e p ten a e move backwa d a d o ard around their hinges they act upon the tables V, and as soon as they arereleased the bellrank le r Wan the spr ng U a t o re urn the tables to their normal position, thus giving h m a l g t ja which wi l. c u e h fruit and any pits which fall with the fruit to move upon he tab es- H le a made in these tables of sufilcien size to allow thepits to fall through, while t e meat, being more bulky, will pass over the surface of the-table and eventually bedischaged into any suitable receptacle.

By means of a hood a, fixed behind the cutter-disk, the its are directed into a convenient receptac e, the hood being slotted to all low the disk to turn through the slot.

Having thus described my invention, what I claim as new, and desire to sec'ureby Let- 'ters Patent, is-

p 1. In a machine for cutting fruit and removing the pits therefrom, the revolving toothed disk having the sharpened edges, the hinged yielding knife operating in conjunction with the disk and in a plane parallel with and close to the disk, and the curved hinged plates having Qdges'whiuh press against the cuttingblade and enterthe cut made in the fruit, said plates acting to pull the meat from the pit while the latter is held between theknife and the rotary disk, substantially as herein described.

2. In a fruit-cutting and pit-removing apparatus, the rotary'toothed disk having the cutting-edges, a yielding knife hinged below and approximately in plane with the disk,

and the curved plates adapted to seize the meat of the fruit and remove it from the pit, in combination with the tables adapted to receive the fruit when it is separated and having holes through which the pits may pass, substantially as herein described.

3. The combination, in afruit-pitting machine, of a rotary teotheddisk having sharpened edges, the yielding knife reciprocating approximately in plane with the disk and acting in conjunction therewith to cut the fruit around the pit, the curved hinged stripping-plates having their edges held in contact wit ,the cutting-blades and adapted to enter the cut ma e-in the fruit,so as to pull it off the pithy the outwardly-swinging motion, and the inclinedperforated tables situated beneath the diskand strippers, having one end connected witl the stripping-plates and the other with the bell crank lever and returningspring, substantially as herein described;
